There is quite a span of time between the casting date of H-28-8 (August 28, 1968) and the assembly date T0210MN (February 10, 1968). That throws the proverbial "red flag" in the air for me.
In addition, the lack of documentation doesn't help to verify/disprove.
The photos show the car as a very nice restoration. A smog system would be a nice touch...but lose that orange-painted engine lift hook!
